Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a seat device for a vehicle, such as a passenger seat for a light vehicle, for example.

(Prior Art) Conventionally, as the sheet device of the above example, for example,
There is an apparatus described in JP-A-58-47632.

That is, the seat bag is divided into a gate-shaped fixed seat bag and a hollow rotating seat bag, and the rotating seat bag is rotatably connected to the above-mentioned fixed seat bag via a link mechanism. When positioned in the opening of the seat back, it is used as a normal passenger seat, and when the above-mentioned rotating seat back is tilted towards the rear, it is set opposite to the rear seat.
For example, this is a seat device for a vehicle that serves as a lounge seat when the vehicle is stopped.

However, such a conventional device has a problem in that two children cannot be seated on the passenger seat.

Here, the need to seat two children in the passenger seat mentioned above is such that, for example, a female driver
This problem occurs when a vehicle is driven with a person in tow, but conventional seat devices have a problem in that it is difficult to seat two small children on the front passenger seat.

(Purpose of the invention) The object of this invention is to provide a seat device for a vehicle that makes it possible to seat two small children by uniquely configuring a normal passenger seat.

(Structure of the invention) This invention divides the seat back into upper and lower halves, an upper seat back and a lower seat back, and connects the lower seat back and the seat cushion with a link so that the lower seat back becomes the front backrest. This vehicle seat device includes an upper seat bag rotatably supported on the vehicle body via a bracket so as to serve as a seat, and a headrest that is movably attached to the upper end of the upper seat bag so as to serve as a rear backrest. It is characterized by

(Effects of the invention) According to this invention, when the lower seat back is fixed in position forward via the above-mentioned link, the lower seat back becomes the front backrest.

Further, when the upper seat back is fixed in a substantially horizontal position via the above-mentioned bracket, this upper seat back becomes the rear seat portion.

Further, when the head rest at the upper end of the above-mentioned upper seat bag, which has been rotated approximately horizontally, is pulled up, this head rest becomes a rear backrest.

For this reason, there is one child between the lower seat back and the seat cushion, which are set as described above.
Since a person or a small child can be seated between the upper seat back and the headrest, a total of two small children can be seated on the passenger seat.

(Example) An example of this invention will be described in detail below based on the drawings.

The drawings show the seat device of the vehicle, and FIGS.
In the figure, this seat device has a seat cushion 4 disposed on a center floor pan 2 on a floor 1 serving as a vehicle body via a slider 3, and a first link 5, a second link 6, and a seat cushion 4.
The seat bag 7 is connected to the seat bag 7 through the seat bag 7, and the seat bag 7 is divided into upper and lower halves into an upper seat bag 8 and a lower seat bag 9, and a headrest 11 can be raised and lowered at the upper end of the upper seat bag 8 via a rotating arm 10. It is installed on.

The lower seat bag 9 mentioned above is the same seat bag 9.
The lower end of the lower seat bag and the approximate center of the seat cushion 4 in the front and back direction are connected to each other by the first link 5 and the second link 6 so that the front backrest A is formed when the seat cushion 4 is pulled forward. It is connected.

Further, the aforementioned upper seat bag 8 rotatably supports the lower back surface of the upper seat bag 8 on the floor 1 via a hinge 12 and a bracket 13 so that it becomes a rear seat part B when the seat bag 8 is moved forward. The upper end of this bracket 13 is set as a pivot point 13a.

Further, the aforementioned head rest 11 is attached to the upper end of the upper seat bag 8 via a rotating arm 8 so that it can be raised and lowered so that it becomes a rear backrest C when the head rest 11 is pulled up rearward. Rotation fulcrum 1 is the lower end of arm 10
It is set to 0a.

The illustrated embodiment is configured as described above,
The action will be explained below.

In order to convert the normal passenger seat shown in FIG. 1 into a seat for two small children as shown in FIG. 2, the seat cushion 4 and lower seat back 9 shown in FIG. As shown, it is slid forward together with the slider 3 and fixed in position.

Next, the lower seat back 9 at the position of the imaginary line α in FIG. The raised lower seat back 9 is set to the front backrest A.

Next, to the space 14 side on the center floor pan 2 formed by sliding each of the aforementioned elements 4 and 9 forward,
The upper seat bag 8 in the state shown in FIG. 1 is rotated forward about the rotation fulcrum 13a at the upper end of the bracket 13 so as to be substantially horizontal, and the upper seat bag 8 is fixed in position as shown in FIG. Set to rear seat B.

Next, the head rest 11 at the upper end of the upper seat bag 8 is moved to the pivot point 10a of the pivot arm 10.
The headrest 11 is pulled up backwards around the center and fixed in position, and the raised headrest 11 is set as the rear backrest C.

In this way, each of the above elements 4, 9, 10, 11
When the front part of the seat cushion 4 and the front backrest A are fixed in position by sliding and rotating the
As shown by the imaginary line in Figure 2, there is a dwarf between
Furthermore, since one child can sit between the rear seat portion B and the rear backrest C as shown by the imaginary line in the figure, there is an effect that a total of two children can sit on the passenger seat.

Note that a ratchet mechanism or the like is used to fix the positions of each of the above-mentioned elements 4, 9, 10, and 11.

3 and 4 show another embodiment. In this embodiment, a spacer fixed on the center floor pan 2 is used in place of the slider 3 of the previous embodiment (see FIGS. 1 and 2). 15, the rotating directions of the upper seat back 8 and headrest 11 are reversed, and the length of the rotating arm 10 is set shorter than in the previous embodiment.

The operation of the embodiments shown in FIGS. 3 and 4 will be explained below. In order to convert the normal passenger seat shown in FIG. 3 into a seat for seating two children as shown in FIG. , lower seat bag 9 in Fig. 3
is pulled forward and fixed in position around the respective lower end pivot points 5a and 6a of the first link 5 and second link 6, and the lower seat back 9 that has been pulled up is
is set on the front backrest A as shown in FIG.

Next, place the upper seat bag 8 under the condition shown in Figure 1.
The upper seat bag 8 is set in the rear seat part B by tilting it backward about the pivot point 13a at the upper end of the bracket 13 and placing the upper seat bag 8 on the floor 1, as shown in FIG.

Next, the head rest 11 at the upper end of the upper seat bag 8 is moved to the pivot point 10a of the pivot arm 10.
The headrest 11 is pulled forward and fixed in position, and the raised headrest 11 is set as the rear backrest C as shown in FIG.

In this way, when each of the above-mentioned elements 8, 9, and 11 is rotated and fixed in position, a small person is placed between the front part of the seat cushion 4 and the front backrest A as shown by the imaginary line in FIG. One child can be seated between the rear seat B and the rear backrest C as shown by the imaginary lines in the figure, so a total of two children can be seated on the front passenger seat. There is.

In this embodiment, as in the previous embodiment, a ratchet mechanism or the like is used to fix the respective positions of the above-mentioned elements 8, 9, 11.

Regarding the correspondence between the structure of this invention and the above-mentioned embodiment, the vehicle body of this invention corresponds to the floor 1 of the embodiment, and the links correspond to the first link 5 and the second link 6 in the same manner. This invention is not limited to the configuration of the above-described embodiment.
